This episode explores a growing tension in sustainability communications that many businesses are quietly navigating. As scrutiny increases, the challenge is no longer just what to say, but whether to say anything at all. Listen in as Katie and Malin unpack what is really at stake.
In this episode, Malin and Katie are joined by their first guest, Sangeeta Waldron, award-winning communications specialist and climate communicator. Together, they explore what honest sustainability communication really looks like in practice, and why the idea of being ‘perfect’ is holding many businesses back. From storytelling to trust, the conversation challenges the need for perfection and encourages a more open, human approach.
In this episode, Malin and Katie introduce their practical 3Cs framework for sustainability communication. They explore why clarity and action need to come before communication, and how transparency helps build trust even when progress is still evolving. It is a useful guide for anyone looking to communicate sustainability in a way that is clear, credible and grounded.
In this episode, Malin and Katie tackle a conversation many organisations are avoiding. What happens when net zero targets are not going to be met? Building on insights from Futerra’s Solitaire Townsend, they explore the tension between ambition and reality, and why honest, transparent communication can be the most credible response.
In this episode, Malin and Katie are joined by Rob Hopkins, co-founder of the Transition Network and leading voice in the climate movement. Together, they explore why hope, imagination and storytelling play a critical role in driving real change. Challenging cynicism and fear-based narratives, the conversation offers a fresh perspective on how we communicate the future and inspire action.
In this episode, Malin and Katie are joined by Caroline Till, founder of TILT and expert in sustainable design and innovation. Together, they explore why sustainability should not sit on the sidelines of innovation but be embedded across everything businesses do. The conversation highlights the risks of silence, the need for consistent communication and how storytelling can help people connect with a more positive vision of the future.
In this episode, Katie is joined by Dean Connell, workspace design consultant and founder of I-AM.D.C. Together, they explore why environmentalism needs a new narrative and how businesses can focus on real impact within their own sphere of influence. The conversation challenges traditional approaches to sustainability and highlights the value of practical action, clearer communication and embedding circular thinking into everyday decisions.
In this episode, Malin and Katie are joined by Charlie Martin, founder and CEO of the Anti-Greenwash Charter and truMRK, two initiatives dedicated to strengthening the credibility of sustainability communications. Together, they dig into the mechanics of trust, the cost of what organisations choose not to say and why sustainability comms might be the most powerful trust-building tool a business has if only more were brave enough to use it.
In this episode, Malin and Katie are joined by Ingmar Rentzhog, entrepreneur, climate communicator and founder and CEO of We Don't Have Time, the world's largest media platform for climate action. Together, they dig into why Ingmar believes the comms and marketing industry is the most under-recruited force in the climate movement and what he thinks it should do about it.
In this episode, Malin and Katie recorded from the middle of the UK's second heatwave of the summer with climate change dominating their feeds. They shared the good news stories they had gathered from furniture passports to tap water with a conscience, as proof that sustainability comms are being done well in plenty of places. This was their antidote to doom-scrolling.
